Two tests had moved without changing, which only made the diff harder to read.

…, squash-merged as DIRACGrid#29)
A value given by mistake, such as a misspelled field or plain data in a CredentialSet, may be the secret itself. Validation errors now hide their input, as the configuration models already do.
The message comes from the consumer's code and may hold a token or a secret URL. The AuthenticationError names only its type; the exception itself is still available as __cause__.
The fields were described in comments, which the generated reference does not show. They now use attribute docstrings, as the configuration models do.
Name every argument and the return value, and drop the blank lines before closing quotes.
For one of several CEs on a host, or a CE behind a forwarded address. The endpoint and schedd end up on the tools' command lines, so they are checked when the configuration is read: neither can pass as an option. Part of DIRACGrid#23.
The contract says inputs are read before submit returns, so an unreadable one is a SpecificationRejectedError, not a raw OSError. The conformance suite now asks for it, and the fake does it. Part of DIRACGrid#23.
Moves test_fake_backend.py to tests/unit/backends/fake/, ready for the HTCondor tests that follow. The tests themselves do not change. Part of DIRACGrid#23.
- process: runs one tool, killing it on a timeout - session: one operation's credentials in private files that exist only while it runs, the tools' environment, and telling a rejected token from an unreachable CE - staging: the private working area, and what a submission puts in it Nothing uses these yet. The backend follows in the next commit. Part of DIRACGrid#23.
Renders a submit description from a plan: one process per copy, per-copy values indexed by ProcId, quoting, and refusing what a description cannot hold. It sets no policy on the job except keeping finished jobs until they are purged, so output can be collected again. Shared with the HTCondor scheduler to come (DIRACGrid#21), so it knows nothing about any backend. Expected values were checked against HTCondor 25. Part of DIRACGrid#23.
Spooled submission to a remote schedd, token authentication, and an optional X.509 proxy for sites that account on VOMS attributes. Copies whose variable names differ get separate clusters, because HTCondor merges each process's environment onto the previous one. Registered as `htcondor-ce`. Kill, purge and output follow in their own branches. Part of DIRACGrid#23.
Builds the tools' command lines and reads what they print: condor_submit -terse, condor_rm, and the job ads of condor_q and condor_history, mapped to the common JobStatus. A finished job's result comes from its exit, a removed job keeps the result it had, and any hold that interCEde did not cause counts as aborted. Part of DIRACGrid#23.
FakeCondor answers the way HTCondor 25 does (checked against a live schedd), so these run without HTCondor installed: credentials, error classification, staging, secrets, containers and the working area. Part of DIRACGrid#23.

…only allow one credential type instead of combinations
interCEde no longer supports proxies, so a description has nothing to say about one.
…ack/htcondor-3-submit-status # Conflicts: # src/intercede/config.py
The credential provider now returns one credential instead of a set, and proxies are gone: no proxy file, and no delegation setting to go with it. The kind is checked once, where the token comes from, so the rest only deals with a token. X509_CERT_DIR stays. It holds the CAs the CE's host certificate is checked against, which has nothing to do with a proxy.

feat: HTCondorCEBackend with submit and status
Part of #23. PR 3 of 6 for the HTCondor-CE backend.
Important
Depends on #30 and #33 (
stack/htcondor-1-core). Merge after both.Until then, this diff also shows them. This PR's own change: 1,688 lines
A consumer can now get an HTCondor-CE backend from the registry (
kind = "htcondor-ce"), submit to it and ask for status. Kill, purge and output follow in PRs 4 and 5. About half of this PR is tests.Reading order (one commit each)

It only raises when nothing was submitted.include_unlisted), and containers need acontainer_launcher.Diagnosable, on purpose.Known issue, not fixed here
submit()raises a rawValueErrorfor a line break in an argument or environment value, a bad variable name, or a comma in an output name. It should be aSpecificationRejectedError. If the bad value is in a later group of copies, the first cluster is already submitted, so that job stays queued and the caller gets no handle for it.Testing
65 new unit tests against simulated tools (
FakeCondor, which answers as HTCondor 25 does), so no HTCondor is needed. Tests against a real CE arrive in PR 6.
